OIL-BURNER.

To all w/wm t may concern.'

`Be it known that I, FRANK W. SMITH, a citizen of the United States, residing at Tulsa, in the county ofTulsa and State of Oklahoma, have invented certain new and useful Improvements 'in Oil-Burners, of which the following 1s al full, clear, and

exact description, reierence being had to the.

accompanying drawings, forming a part hereof.

My invention hasrelation to improvements in oil burnersa'and it consists in the novel construction of burner more fully set forth in the specication and pointedout in the claim.

'Ihe present improvement -is more particularly directed to burners operating on hydrocarbons suoli as crude petroleum, lg'asolene, kerosene and the like, theV object being to provide the burner with a vapor generator 'which will prevent any material drop in the temperature of the vapor discharged therefrom on its way to the mixing chamber, the present improvement contemplating the simultaneous heating of the walls of the generator member as well as the member into which'themixture of air and vapor is discharged from the mixing chamber, said member in the present construction constituting the burner heador cap as presently to beseen. l v

A further object is to provide ymeansV of effecting an even distribution of the mixture.

to the burner head; to provide effective means against leakage 'by the elimination of screw joints; to provide a burner which may be attached to any existing coal or Woodburning stove; one which Vis simple, cheap and durable, and one possessing further and other advantages better apparent from a detailed description of the invention in connec'tion with the accompanying drawings, in

which-y Figure l represents a side elevation of ay Y conventional stove body showing my invention applied thereto; Fig. 2 is a side elevation of the burner, with vfuel-feed pipe in vcross-section and with part ofthe burner head removed; Fig. 3 is a top plan ofthe burner with the bulk of the burner head removed;V Fig.,4 is a vertical cross-section vron the line 4*4 of Fig. 3; and Fig. 5 is a vertical longitudinal section Von the line 5-5 ofFig. 3.

Referring to the drawings, S reprcel t; conventional coal `stove' and F lthe iire pot thereof as well understood in the art. Adapted to be inserted into the fire-pot and secured therein in any mechanical manner is my improved burner, the same comprising a plate or disk l provided with a central opening U, said plate forming a supporting platform for the detlector or distributer member 2 mounted directly above the opening, and secured Vto the platform through the feet a. Depending from the edge of the plate l is aboss 3 traversed by a central passageway or duct /t whose upper end or that adjacent theplatform l is enlarged to receive an inner plug of Babbitt metal m and outer plug of hre-proof cement n, said plugs receiving the discharge terminal 4 of the vaporizer coil or conduit 4 disposed contiguous the outer edge of the platform l. Preferably, the terminals of the feet a of the distributer 2 are interposed between the coil 4Aand platform l. lhe coil 4 is provided vvith an intake extension 4 disposed in the general plane of the coil, said extension vpassing through an arm or boss 5 formed with the platform l, andextending into the discharge end of the fuel-feed pipe P screwed into said boss. rIhe outer terminal of the boss 5 is formed with a socket for receiving ka perforated plug 6 of Babbitt metal through which the pipe 4 passes and against which the inner end of the pipe P abuts, the babbitting of the pipe 4 to the plug Y6 making an absolutely tight or At the inner end of the boss' is likewise formed a socket for receiving an inner perforatedv Babbitt plug 7 and an outer ring'of lire proof cement 8 through whihthe pipe 4 passes, the babbitting of the-pipe 4 to the plug 7 likewise insuring a leak-proof joint.

Leading from the lower terminal of the boss 3 is'a horizontal leg 3 provided with a passage-way It communicating with the passage-way or duct It of the yboss 3, the outer end of the passage It terminating in an enlargement h from which leads a discharge port t formed in the wall of the leg 3', the axis of the port being coincident with the axis of the opening O through which the mixture of vaporized oil and air formed in the air gap G is projected against the distributer or delector 2.. The gap G serves as,

and performs the-k function y of, a `mixingr chamber as obvious from the drawings. The discharge terminal of the duct h 1s 4controlled by aneedle valve 'u at theinner terV minal rof a screvv valve stem 9 operating in the front Yof the stove S, and terminating on the outside in a handle 9 byY which the Y stem may be manipulated and thus the flowof the vapors from the duct a/` controlled. sseen from thedrawings, the axes ofthe leg 8 and boss are at vright angles to oneV another, but disposed in parallel planes.

Surmounting the vplate or platformV l is a dome yor arch shaped burner-,head or cap B provided With burner'openings o, the edge of the burnerLhead resting on the' plate l I adjacent the periphery` of the latter, as

shown, the Walls of the burner head being;

' ysuitable y platfornuV a `vaporizer conduit Y mounted on top of the samea-nd dischargzjirel through andv to one lside'Y thereof, a member Y space d'from the deiiector 2 and the arms' z thereof, and forming WithY the supporting i platform'l a collectingichamber C for the Y suring the heating of the Walls of lthe legrv 35V mixture which pours through the openings 0. Secured to the bottom of the boss 8 be# neath the leg 8 is avstarting pan or equivalent holder Ii for alcohol or other fuel by the burning of which the Walls of the leg` 3 are initially heated tov properly start thev burner. y c y The operation 'of the burner Vis substan-v tially as follows: Alcohol having been first poured into thepan II is ignited thereby in- 3, The valvew'is then moved to open position (the liquid hydrocarbon or fuel' being previously turned `on to flow into thepipe P), the oil thus flowing through the pipe e, coil 4, extension 4, passage h, and passageV It', and being vaporized by its 'contact` The with. the heated metal of the burner.

vapor is Vprojected from'the port t across the gap G formingthe mixing chamber into the. collecting or distributing Lchamber C through the opening O, escapingy throughthe burner. openings 0 When lthe same may be ignited.V In traveling across the 4gap G,

I' vmayof course depart ina measure,'fromV the details here shown Without n1 any Wise affecting the nature orfspiritof the invention. Preferably, the boss 5gis removedYan-r gularly from the leg 3V (inthe presentinstance ninety degrees) vs'or'as to dischargev into the chamber Cin a direction transverse to the'leg 8this arrangement bein'gressential 'for obvious reasons, particularly to per# mit ofthe proper installation'of the burnerVVV il.
